Tegal - Plasma Inline 700 Single Wafer Etcher

This little bench-top planar plasma etching system was king of the mountain in the United States back in the early eighties. One of the first planar electrode systems to be successfully introduced into the factory environment, it offered good etch uniformity and rapid end-point detection to shut down the plasma when silicon dioxide was no longer detected in the throw-off.

The company was founded by Ted Gallagher, who also provided its name from the first few letters of his own. At the time it was exceeded in size only by its main competitor, Tokyo-Ohka of Japan.
